Yes, probably the same bug that caused problems with the Virocop WHD install that I read in another thread (well, that Predseda pointed me to).
But I've got around this as I've added an option on the title screen to choose between normal joystick control and the CD32 pad. And - as Ironclaw correctly pointed out in his video (thanks for being eagle-eyed!) - the collision issue was because I hadn't resized the ladybird sprites correctly, so there were loads of invisible pixels on them that registered a collision. This enemy was added quite late in place of a green one the same shape which I did resize so that was introduced almost at the end. Anyway, now fixed
So hopefully v1.1 will be on the site sooner rather than later, I've uploaded it for it to be placed on the site and will let you know when it has.
